ISC BIND Assertion Failure Vulnerability

Low Nessus Plugin ID 122506

Synopsis

The remote name server is affected by an assertion failure vulnerability.

Description

According to its self-reported version, the instance of ISC BIND 9 running on the remote name server is less than 9.11.5-P4 / 9.11.5-S5 / 9.12.3-P4 / 9.13.7. It is, therefore, affected by an assertion failure vulnerability.

- An assertion failure exists in the managed-keys component due to an error when, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. An unauthenticated, remote attacker to cause named to deliberately exit after encountering an assertion failure.
(CVE-2018-5745)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to ISC BIND version 9.11.5-P4 / 9.12.3-P4 / 9.13.7 or later.
